A New Micro-Respirometer with Automatic Setting and Recording Apparatus

PETER TUFT 1

1 Department of Zoology, University of Cambridge

A new micro-respirometer is described, capable of measuring rates of volume change from 5 µl./hr. down to 0.01 µl./hr. to the nearest 0.001 µl. It is a constant-pressure nul-reading instrument and the actual volumes of gas absorbed or evolved are obtained from readings of the instrument by a simple multiplication.

A device is described which sets the instrument automatically and records the volume changes at regular intervals.
